Abstract
The invention discloses a core assembly pouring device for a cylinder body casting in an automobile engine, comprising a base plate (4), two raiser cores (2), a sprue core (3), sand core assemblies (1) and a locking device (5), wherein the sand core assemblies (1) are connected on the base plate (4) and are locked by the locking device (5), the raiser core (2) and the sprue core (3) are located on the two adjacent sand core assemblies (1) which are clamped on the base plate (4), and the locking device (5) is sleeved and pressed outside the two sand core assemblies (1). By adopting the structure, the sand core of the cylinder body consists of a plurality of sand cores, and each sand core is composed of a plurality of small sand cores, thus reducing the size of each sand core, being beneficial to the forming of the sand cores and reducing casting defects of castings; and meanwhile, the number of the sand core assemblies is two, e.g. one die generates two castings, thus greatly improving production efficiency.
Description
Technical field
The present invention relates to the metal casting technical field, specifically is the core assembly pouring device of cylinder block casting in a kind of automobile engine.
Background technology
Cylinder body in the automobile engine is normally formed by casting, and its structure is very complicated, and casing wall is thinner, and it is bigger therefore to cast difficulty, and percent defective is higher.At present, the cylinder body in the automobile engine has two kinds of pouring types, and a kind of is that high-pressure molding line comes the moulding cast after adopting coremaking, and another kind is to adopt core assembly pouring.But there is following shortcoming in these two kinds of pouring types:
1) for first kind of pouring type, because mo(u)lding line equipment price costliness, this pouring type only uses in large enterprise; Simultaneously, it is to adopt horizontal pouring technology, and the water jacket wall of its cylinder body approaches and easy deformation, therefore, and percent defective height, production cost height.
2) for second kind of pouring type, because the core that designs in the technological design process is bigger than normal, core is not easy moulding when doing core like this, and can produce the casting flaw of foundry goods; In addition, each core must be next fastening with bolt during core assembly, increases production process; Simultaneously, generally all be single-piece production, promptly a sand mold can only go out a product; Therefore production efficiency is lower.
Summary of the invention
Technical problem to be solved by this invention is that the core assembly pouring device of cylinder block casting in the automobile engine that a kind of production cost is lower, production efficiency is higher is provided.
For solving the problems of the technologies described above, the core assembly pouring device of cylinder block casting in the automobile engine provided by the invention, comprise base plate, rising head core, gate core, core group and locking device, described core group is connected on the base plate, and by locking device locking, described rising head core and gate core are positioned on the core group, and described core group is adjacent two groups, all be connected on the base plate, the rising head core also is two; Described locking device cover is pressed in the outside of two groups of core groups; Described every group of core group comprises base plate core, front end core, several cylinder barrel cores that are arranged in parallel, jacket core, rear end core, left plate core and right plate core; Wherein, two groups right plate core is adjacent and all be connected to the base plate middle part, and gate core is positioned at the centre of adjacent two right plate core end faces; Described base plate core is slidingly connected on the base plate; Described jacket core has and the identical hole of cylinder barrel core quantity; Described cylinder barrel core all is connected on the base plate core, and corresponding one by one being linked in the hole of jacket core; Described cylinder barrel core is connected on the base plate core, and described front end core and rear end core are connected to respectively on two cylinder barrel cores in two of the cylinder barrel core that is arranged in parallel, and the two ends of described rising head core are connected to respectively on the end face of front end core and rear end core.
The middle part of described base plate has two draw-in groove I, and two, described right plate core bottom surface has two projection I, and described two projection I are embedded in respectively in two draw-in groove I; Have a draw-in groove II on the described base plate core, left plate core bottom center has a projection II, and described projection II is embedded in the draw-in groove II on the base plate core.
Described base plate left and right sides two parts all have dovetail groove, and the profile of described base plate core and dovetail groove match and be slidingly matched with dovetail groove.
Described front end in-core side has projection III, and rear end in-core side also has projection III, and the outside of described two the cylinder barrel cores in cylinder barrel core two that are arranged in parallel has the draw-in groove III that matches with projection III respectively.
Described locking device is the locking briquetting with rectangular opening, and described two groups of core groups are positioned at rectangular opening simultaneously and match with it.
After adopting above structure, the present invention compared with prior art has the following advantages:
1) since cast gate of the present invention, rising head all at the top of core, promptly adopted the casting technique of upright casting rising pouring, solved cylinder body water jacket, reduced the quantity of foundry goods inner air vent owing to the problem on deformation that thin-walled produces, thereby improved the product qualified rate of foundry goods, reduced production costs greatly.
2), help the moulding of core and reduce the casting flaw of foundry goods again because the core of cylinder body is made up of several cores, and promptly core is made up of several little cores, and each core is diminished; The core group is connected on the base plate, and incompatible locking is overlapped by locking device in core group outside, has saved the production process of bolt tightening; Simultaneously, the core group is two, and promptly a mould goes out two foundry goods; Generally speaking, improved production efficiency greatly.
